fix: nil load-file-name in package autoloads

Browse Source 
Some packages do funky things in their autoloads, so care is needed to
closely emulate an autoloading environment when loading them, however,
in 8cafbe4, Doom wraps these autoloads in a function, thus ensuring
they're executed without `load-file-name` or `load-in-progress` set,
which some packages will expect these in their autoloads.

This fixes the (wrong-type-argument stringp nil) error some folks see
with certain packages doing said funky things in their autoloads (like
realgun in the :tools debugger module).

Fix: #8143
Amend: 8cafbe4408
